Chapter 5. Enhancing Pages with Graphics... > Understanding Image Basics

Understanding Image Basics

Graphics inserted into a Web page are called inline images. The two most common graphic file formats for Web publications are Graphics Interchange Format (GIF) and Joint Photographic Experts Group (JPEG). All graphics-capable browsers support these two formats and display them without fuss. If you stick with these, everybody will be able to see your images.

Note

Portable Network Graphics (PNG) format is a newer graphics format that has been suggested as a better standard for Web images. It supports True Color, which makes it better for photographic images than GIF; also, unlike JPEG, its compression is lossless (that is, its quality is not degraded when the image is compressed). It is making inroads very slowly, however, and may never replace GIFs and JPEGs.
